| 摘 要： | 渔业技术进步对渔民持续增收有何影响尚存争议。本文基于2004—2014年中国省级面板数据,运用两阶段最小二乘法和门限面板模型分别对捕捞和养殖技术进步的增收效应展开检验。结果显示：①沿海地区捕捞和养殖技术进步均对渔民增收具有显著的正效应;内陆地区仅养殖技术进步增收效应显著,捕捞技术进步的增收效应不明显。②当地方人均GDP低于18792元时,捕捞和养殖技术进步的渔民增收效应不明显;当地方人均GDP高于18792元时,捕捞和养殖技术进步对渔民增收的积极效应开始显现,随着经济发展水平的不断提高,捕捞和养殖技术进步的增收效应越来越大。③当城乡市场分割较为严重时,捕捞和养殖技术进步的增收效应不明显;当城乡市场一体化水平提升到一定程度,捕捞和养殖技术进步的增收效应显现。④捕捞和养殖技术进步增收效应的发挥以一定的城镇化率为门槛,当城镇化率高于0.460时,捕捞和养殖技术进步的增收效应显著。本文为如何贯彻实施“科技兴渔”战略,更好地促进渔民增收提供经验支持。 |

| Abstract: | Whether fishery technology progress leads to continuous increase in fishermen’s income is contraversial. Based on provincial panel data in China from 2004 to 2014, the two-stage least squares method and a threshold panel model were used to test the effect of fishing technology progress and aquaculture technology progress on fishermen’s income respectively. The results showed that: (1) Fishing technology progress and aquaculture technology progress in coastal areas had a significant positive effect on fishermen’s income, while in inland areas, only aquaculture technology progress had a significant effect on fishermen’s income, but the effect of fishing technology progress was not obvious. (2) When the per capita GDP was less than 18792 yuan, the effects of fishing technology progress and aquaculture technology progress on fishermen’s income were not obvious. When the per capita GDP was higher than 18792 yuan, the positive effects of fishing technology progress and aquaculture technology progress on fishermen’s income began to appear. The higher the economic development level, the greater the effect of fishing technology progress and aquaculture technology progress on fishermen’s income is. (3) When the market segregation between urban and rural areas was serious, the effects of fishing technology progress and aquaculture technology progress on fishermen’s income were not obvious. When the level of integration of urban and rural markets rose to a certain extent, the effects of fishing technology progress and aquaculture technology progress on fishermen’s income appeared. (4) The effects of fishing technology progress and aquaculture technology progress on fishermen’s income were related to urbanization rates. When the urbanization rate was higher than 0.46, the effects of fishing technology progress and aquaculture technology progress on fishermen’s income were significant. The study provides empirical support for implementing the strategy of “invigorating fisheries by technology” and increase fishermen’s income. |
